Recently, I was asked to give a seminar for @mhclgโs planners on the challenges faced by local authority planners delivering against the #climateemergency, because I work with lots of councils & Iโm also Cabinet Member for Forward Planning at @CotswoldDC. So I know some stuff.
First up, I did the โweโre all doomedโ bit. You know, the rollercoaster graphs steeply going up and the even steeper graphs of how emissions need to come down.
Then I mentioned about how most plans are running for about another 10-15 years and they need re-writing immediately because most of them pay diddly-squat attention to the โwhat goes up must come down graphsโ from the โweโre all doomedโ bit.
